I had my android mobile as a seeder & Vuze & utorrent as leachers (in the same LAN network), but I was able to leach on only one software on my PC, at a time.
I tried many times, but was not successful in downloading through both softwares simultaneously.

In other words, it can be said that Vuze app for android can be a seeder for only a single peer.

Just one help for users:
How I leached from utorrent on PC:
I added the same torrent to utorrent on my PC.
After adding, I clicked on it & then in the below description in utorrent, clicked on peers.
Now I right-clicked & clicked on "Add peer", & in the IP Address option, I entered the localIPaddress:PORT of my android mobile. eg. 192.168.0.110:43524

I got PORT number by:
opened Vuze app, touch on-screen menu button>>Settings>> & you can see your port under "Incoming TCP Port".

There is a config option to allow multiple connections but you can't get it on the Android app as there is no UI to change it.

As you said, I tried Vuze android app as a seeder for two different PCs in the same LAN. & it was able to seed to both computers simultaneously.
So the answer to this thread is: Vuze app supports more than 1 local peers.
